JAR-FASTEN ER.

SPEGIFICATION forming part of Letters Patent No. 545,684, datedSeptember 3, 1895.

' Application filed June 21, 1895. Serial No. 553,550- (No model.)

To aZZ whom it may concern: I

Be it known that I, MARK L. DEERING, of Brooklyn, in the county of Kingsand State of New York, have invented a certain new and usefulImprovement in Jar-Fasteners, of which the following is a full, clear,and exact description, reference being made to the accompanyingdrawings, forming part of this specification.

This invention relates to improvements in fastening devices which areadapted to secure the cover of a jar-such as a fruit or preserve jar-inits seat so as to faciliate and render permanent the sealing of the jar;and the invention consists of a fastening device comprising a yoke, avertically-movable bar spanning the yoke and secured by its ends to thearms thereof, and a cam adapted to depress the bar against the cover ofthe jar, the device having its several parts constructed and arrangedsubstantially as described and claimed herein.

In the accompanying sheet of drawings, Figure 1 is a top view of the thefastener applied to a jar; Fig. 2, a view of the jar and fastener inelevation; Fig. 3, a vertical section of the jar and fastener in theplane a: m Fig. 1; and Fig 4 shows thefastener alone in elevation.

Similar reference-numbers designate like parts in the difierent views.

The object of this invention is to simplify and otherwise improve thestructure of the jar-fastener, which comprises a cross-bar that isadapted to bear upon the cover of the jar at or near the margin thereofand at places on opposite sides of its center, so as to distribute thepressure on the cover and not subject it to a strain upon the centerthat might be great enough to break it.

This fastener may be made entirely from wire and its several parts maybe formed by automatic machinery. Its necessary cost is therefore muchless than that of the fastener now in use, which it most nearlyresembles, and on which itis an improvement.

The jar 1 is provided near its mouth with a bead-like projection 10, onwhich is the seat for the rubber packing-ring 11 and cover 2. The uppersurface of the cover is slightly concave, as indicated in Fig. 3.

The yoke of thefastener is made by bendin g astrip of metal, preferablya piece of steel wire, into the form represented in the drawings. It hasthe main part or section 3 and arms 30 extending downward from it atright angles, the lower ends of the arms being bent inward, as shown at31. The cross-bar 4, which is made from smaller wire than that of theyoke, extends from one arm of the yoke to the other, being parallel tothe main section of the yoke when there is no strain upon it andpreferably directly underneath that section, and it is secured to theyoke by bond ing the wire at the ends of the cross-bar around the arms30 of the yoke in such a manner that the cross-bar may move freely upand down thereon. At one end of the cross-bar the wire is coiled severaltimes around the arm, as shown at 40, to prevent the cross-bar fromturning too much. The piece of wire fromwhich'the cross-bar is made islonger than is required for the cross-bar alone, and from that partwhich is not needed for the cross-bar is formed a stop 5, which projects7 5 laterally from the cross-bar and yoke 'and renders it easy to locatethe fastener in its proper position on the jar. This part of the wireextends from the coil or eye 41, at the left end of the cross-bar inFigs. 1, 2 and 4:, parallel to and by the side of the cross-bar nearlyto the middle thereof, as shown at 50, thence outward from thecross-bar'horizontally and at right angles thereto, as shown at 51', fora distance substantially equal to one- 8 half the diameter of the coverof the jar, thence vertically downward and back, forming the stop at 5,and thence horizontally back tothe cross-bar and along the cross-bar, asshown at 52 and 53, to the arm of the yoke, around which the end of thewire is bent.

To the yoke, at the middle of the main section 3, is fixed a devicehaving the function of a cam or screw and adapted to apply pressure in adownward direction upon the cross- 5 bar 4. It consists of two coils ofwire, one within the other, the inner coil'6 being rigidly secured tothe yoke by means of the part 60 bent around the section 3 and the outercoil 7 being adapted to travel upand down on the ICC inner coil, as anut travels on a bolt and being provided with a finger-piece or handle70,

whereby it may be turned. The bottom of the coil 7 rests normallyagainst the cross-bar 4. when the coil is in its highest position andthe cross-bar lies upon the cover of the jar.

To apply the fastener to a jar and secure the cover of the jar in itsseat by means thereof the fastener is placed on the jar with thecross-bar resting on the cover close to its edge. Then it is movedhorizontally, so that the inwardly-bent parts 31 of the arms of the yokepass under the head 10 on the jar, and when the stop 5 is in contactwith the edge of the cover the coil 7 is turned by means of the handle70, as indicated in Fig. 2, depressing the cross-bar at against thecover so as to hold it securely in its seat. Ihe cross-bar bears againstthe cover, as will be seen, at places near the edge, where the cover isbest adapted to resist strain, the middle of the cross-bar being bentdownward by the pressure into the concave face of the cover.Furthermore, the cross-bar acts as a tie to prevent the arms 30 of theyoke from spreading and slipping off the head 10. It therefore enablesthe yoke to be made from comparatively small wire. Hence fastenersconstructed as above described have all the advantages of those comprising a yoke made from malleable or wrought iron and a cross-barextending through the yoke at right angles to its length, while they aremade from lighter materials, in less time, and with less labor andexpense than are fasteners of the other construction.

Having thus described my invention,what I claim as new, and desire tosecure by Letters Patent, is

1. A jar fastener comprising a yoke having the main section 3 and arms80 with inwardly bent portions 31 at their lower ends, a verticallymovable cross-bar 4 spanning the yoke and secured by its ends to thearms thereof, and a cam or screw mounted on the yoke and adapted todepress the cross-bar, substantially as described.

2. A jar fastener comprising a yoke having the main. section 3 and arms30 with inwardly bent portions 31 at their lower ends, a verticallymovable cross-bar 4: spanning the yoke and secured by its ends to thearms thereof, a cam or screw mounted on the yoke and adapted to depressthe cross-bar, and a stop 5 projecting laterally from the cross-bar andyoke and adapted to make contact with the edge of the jar cover,substantially as described.

3. A jar fastener comprising a yoke formed from wire and having the mainsection 3 and arms 30 with inwardly bent portions 31 at their lowerends, a vertically movable crossbar 4; spanning the yoke and securedbyeyes or coils at its ends to the arms of the yoke, and a cam or screwmounted on the yoke and adapted to depress the crossbar, substantiallyas described.

4. A jar fastener comprising a yoke formed from wire and havingthe mainsection 3 and arms 30 with inwardly bent portions 31 at their lowerends, a vertically movable crossbar 4 spanning the yoke and secured byeyes or coils at its ends to the arms of the yoke, a stop 5 formed fromthe same piece of wire as the cross-bar and projectinglaterally from thecross-bar and yoke and adapted to make contact with the edge of the jarcover, substantially as described.

5. A jar fastener comprising a yoke having the main section 3 and arms30 with inwardly bent portions 31 at their lower ends, a verticallymovable cross-bar 4: spanning the yoke and secured by its ends to thearms thereof, and a device for depressing the cross-bar composed of aninner coil 6 fixed to the yoke, and an outer coil 7 provided with ahandle and adapted to bear against the cross-bar, substantially asdescribed.
